Description
- The present application claims the benefit of and priority to U.S. Provisional Application Ser. No. 61/247,650 filed on Oct. 1, 2009, the entire contents of which are incorporated by reference herein.
- 1. Technical Field
- The present disclosure relates to a wound closure device and, more particularly, to a wound closure device having a ferrule ejector system for suturing a wound.
- 2. Description of Related Art
- Puncture wounds, wounds that pierce through tissue, may result from trauma or may be intentionally created in order to provide access to a body cavity during surgical procedures. During endoscopic surgical procedures, for example, a trocar device is utilized to puncture the peritoneum to provide an access port by way of a cannula through the abdominal wall. Generally, a trocar and/or cannula is placed through the abdominal wall for introduction of surgical instrumentation which is necessary to carry out the surgical procedure. In this manner, the surgeon may introduce a surgical instrument such as a grasper, scissor, clip applier, stapler or any other surgical instrument which may be necessary during the particular surgical procedure. Once the procedure is complete, it is necessary to suture the wound.
- Conventional instruments for closing puncture wounds generally include a shaft that can be extended into the body through either the puncture wound itself (in the case of a puncture caused by trauma) or through a cannula (in the case of a puncture created to access a surgical site). Suture retaining needles are then deployed from the shaft into tissue. Unfortunately, the mechanisms used for deploying the needles are often cumbersome and may make the extension and/or retraction of the suturing device difficult.
- In the prior art, U.S. Pat. No. 5,470,330 discloses a suturing instrument for closing trocar puncture wounds.

U.S. Pat. No. 6,911,034 discloses a suturing apparatus including one or more arms having a suture mounting portion and one or more needles. Each arm is extendable from the apparatus to penetrate tissue, while each needle is advanceable to a position adjacent an arm to capture the suture mounted thereon and to draw the suture back toward the suturing apparatus. U.S. Pat. No. 7,235,087 discloses an articulating suturing device having an articulating foot. The foot includes suture attachment cuffs configured to engage needles for withdrawing the cuffs through tissue. U.S. Pat. No. 7,449,024 discloses a suturing device having arms that are extendable from the suturing device. Needles may then be advanced into engagement with the arms to retrieve a suture from the arms. U.S. Patent Application Publication No. 2006/0030868 discloses a suturing device including a pair of wings that are selectively extendable from the device. Needles carrying sutures thereon may then be advanced through tissue and into engagement with the wings to retain the sutures thereon. U.S. Patent Application Publication Nos. 2008/0045979 and 2009/0157105 disclose articulating suture devices similar to that disclosed in U.S. Pat. No. 7,235,087, discussed above.

Upon distal translation ofplunger 250, i.e., when an operator depressesplunger 250,distal end 256 ofplunger 250 repositions, or translatesbar 470 distally.Spring 254 is configured to biasplunger 250 toward the position shown inFIGS. 1 and 2 , e.g., a proximal-most position. Thus, in order to depressplunger 250 and translatebar 470 distally, the operator must overcome the biasing force ofspring 254. - Initially, when
plunger 250 is disposed in an at-rest, or proximal-most position, rotatingplate 410 is disposed in the first position, whereinbase plate 410 is positioned substantially perpendicular toshaft 200 such thatferrule holders shaft 200, as shown inFIGS. 1-3 . This first position corresponds to the use position of suturingdevice 10, as will be described in greater detail below. - When
plunger 250 is depressed distally, e.g., in the direction of arrow “A,” as shown inFIG. 4 ,bar 470 is urged distally throughconduit 130 bydistal tip 256 ofplunger 250. Accordingly,arm 460, which is rotatably secured to bar 470 atsecond end 464 viapivot pin 468, is pulled distally in the direction of arrow “A” with respect toshaft 200. Asarm 460 is pulled distally, rotatingplate 410 is rotated in the direction of arrow “B” due to the pivotable connection ofend 412 ofrotating plate 410 withend 462 ofarm 460. Upon further distal translation ofplunger 250, and thus bar 470, rotatingplate 410 is rotated to the position shown inFIG. 4 . In this second position, rotatingplate 410 is aligned withshaft 200 such thatrotating plate 410 does not extend beyond the dimensions ofshaft 200, i.e., such thatrotating plate 410 is positioned substantially parallel with respect toshaft 200. As such, in this second position, or insertion position, suturingdevice 10 defines a minimum diameter to facilitate insertion through an opening in tissue. It is also contemplated that suturingdevice 10 include a locking mechanism (not shown) configured to lockrotating plate 410 in one or both of the first and second positions. - In preparation for suturing, a middle portion of
suture 600 is retained withinlumen 320 ofhead portion 300. One end ofsuture 600 is then attached toferrule 435, while the other end ofsuture 600 is attached toferrule 445. Next,ferrules ferrule lumens ferrule holders ferrule assembly 400. At this point, suturingdevice 10 is configured, or loaded for use. Once suturingdevice 10 is loaded for use,plunger 250 may be depressed to rotaterotating plate 410 to the second, or insertion position, as shown inFIG. 4 such thatsuturing device 10 may then be inserted into an opening in tissue. -
Suturing device 10 is inserted, starting withhead portion 300, through an opening (wound) in tissue that is to be sutured. Thesuturing device 10 is translated through the wound until theferrule assembly 400 is disposed adjacent an interior surface of tissue to be sutured. Once positioned accordingly,plunger 250 may be released, thereby allowingplunger 250 and, thus bar 470, to translate proximally back to the first, or at-rest position, e.g., the use position, as shown inFIGS. 1 and 2 . More specifically, asbar 470 is translated proximally,rotatable plate 410 is rotated to the first position such thatferrule lumen 432 offerrule holder 430, which housesferrule 435, is disposed adjacent a first side of the wound and such thatferrule lumen 442 offerrule holder 440, which housesferrule 445, is disposed adjacent an opposite side of the wound. Thus, it is envisioned that a length of rotatingplate 410 be configured according to the diameter of wound to be sutured. It is also envisioned that rotatingplate 410 andarm 460 are removable from suturingdevice 10 such that an operator may select a rotatable plate and corresponding arm having a length sufficient to allow theferrule holders - Continuing with the operation of
suturing device 10, onceferrule assembly 400 is inserted through the wound in tissue and is moved back to the first position, whereinferrule holders ferrule lumens needle 500 is inserted throughguide lumen 120 ofhousing 100, as shown inFIGS. 1 and 2 . Asneedle 500 is translated distally throughguide lumen 120,guide lumen 120 directsneedle 500 through tissue and towardferrule 445 due to the alignment ofguide lumen 120 andferrule holder 440, whenferrule assembly 400 is in the first position. Upon further distal translation ofneedle 500,distal tip 510 ofneedle 500 passes completely through tissue and eventually entersferrule lumen 442 offerrule holder 440. Asneedle 500 is urged distally intolumen 442,needle 500 surroundsferrule 445 such thatferrule 445 is disposed throughlumen 520 ofneedle 500.Lumen 520 may have a slightly smaller diameter thanferrule 445 such that whenneedle 500 is urged aroundferrule 445,ferrule 445 becomes lodged withinlumen 520, fixedly retainingferrule 445 therein via a male-female friction-fit engagement. Alternatively,lumen 520 may taper proximally fromdistal tip 510 from a first diameter which is larger than the diameter offerrule 445 to a second diameter which is smaller than the diameter offerrule 445. In this configuration, further urging ofneedle 500 aroundferrule 445 engagesferrule 445 withinlumen 520 in a male-female friction-fit engagement. In another alternative embodiment,needle 500 may define a sufficiently small diameter to engage a lumen (not shown) defined inferrule 445. In this embodiment,needle 500 may be urged into the lumen defined inferrule 445 such that theferrule 445 andneedle 500 are engaged in a male-female friction-fit engagement. While described with reference toferrule 445, it is envisioned that any of the above-mentioned configurations ofneedle 500 andferrule 445 may be similarly used with respect toferrule 435 and/or adifferent suture passer 500. It is also envisioned that other suitable mechanisms or configurations for engagingneedle 500 andferrules - Once
ferrule 445 is retained withinlumen 520 ofneedle 500,needle 500 may be pulled proximally, or retracted fromferrule holder 440. Asneedle 500 is pulled further proximally back through tissue,ferrule 445 is removed fromferrule lumen 442.Needle 500 and, thus,ferrule 445 andsuture 600, are translated proximally through tissue untilneedle 500 andferrule 445 have passed completely through tissue, leavingsuture 600 disposed through tissue on one side of the wound. More specifically, the end ofsuture 600 engaged toferrule 445 extends proximally through tissue, while the middle portion ofsuture 600 remains disposed withinhead assembly 300, which is disposed within tissue, i.e., on a distal side of tissue.Needle 500 is then removed fromguide lumen 120 andferrule 445 is separated fromneedle 500. - Next,
needle 500, or a new needle substantially similar toneedle 500, is inserted intoguide lumen 110 ofhousing 100.Guide lumen 110 directsneedle 500 through tissue on the opposing side of the wound and towardferrule holder 430. Similarly as described above,needle 500 is then translated further throughferrule lumen 432 offerrule holder 440 to engageferrule 435 therein in a male-female friction-fit engagement.Needle 500 andferrule 435 are then translated proximally back through tissue, as described above, such thatsuture 600 is disposed through tissue on an opposing side of the wound.Needle 500 may then be removed from the wound andplunger 250 may be depressed to rotaterotating plate 410 to the second position, as described above. Suturinginstrument 10 may then be removed from the wound, leavingsuture 600 disposed through tissue on both sides of the wound with the middle portion ofsuture 600 interconnecting the ends thereof on a distal, or internal side of tissue.Head assembly 300 may be configured to releasesuture 600 therefrom upon removal of suturinginstrument 10 from the wound in tissue, orsuture 600 may be manually released fromhead assembly 300 upon removal of suturinginstrument 10. Once suturinginstrument 10 has been removed, the operator can then tighten and tie off the free ends ofsuture 600 to close the wound. - From the foregoing and with reference to the various figure drawings, those skilled in the art will appreciate that certain modifications can also be made to the present disclosure without departing from the scope of the same. While several embodiments of the disclosure have been shown in the drawings, it is not intended that the disclosure be limited thereto, as it is intended that the disclosure be as broad in scope as the art will allow and that the specification be read likewise.
